The concept of the Blended Wing Body (BWB) aircraft emerged in response to the need for environmentally sustainable airplanes that offer strong aerodynamic performance and reliability for the efficient transportation of large numbers of passengers over long distances at a low operating cost. The BWB aircraft represents a significant advancement in aviation design, providing a platform for the integration of advanced technologies and concepts like laminar design techniques, jet flaps, and distributed propulsion. These innovations offer aerodynamic advantages and hold great promise for benefiting society. However, despite these advantages, the production of BWB passenger transport planes for conventional airlines faces several challenges. This article provides a summary of research findings related to BWB aircraft design, with a focus on the design issues that have hampered the extension of a BWB passenger transport aircraft. According to the research, to connect the full potential of the intricately integrated BWB concept while mitigating its drawbacks, a collaborative design approach that emphasizes refinement, reliability, and operational efficiency should be pursued. This design process should also take into account factors such as cost-effectiveness and noise reduction while optimizing handling characteristics. © 2024 Elsevier B.V., All rights reserved.
